Faraday Tomography with Sparse Modeling
Kazunori Akiyama, Takuya Akahori, Yoshimitsu Miyashita +4
Faraday tomography (or rotation measure synthesis) is a procedure to convert linear polarization spectra into the Faraday dispersion function, which provides us with unique informa…
An Image Reconstruction Method for the X-ray Telescope System with an Angular Resolution Booster
Mikio Morii, Shiro Ikeda, Yoshitomo Maeda
We propose an image reconstruction method for an X-ray telescope system with an angular resolution booster proposed by Maeda et al.(2018). The system consists of double multi-grid…
"Slow-Scanning" in Ground-Based Mid-Infrared Observation
Ryou Ohsawa, Shigeyuki Sako, Takashi Miyata +8
Chopping observations with a tip-tilt secondary mirror have conventionally been used in ground-based mid-infrared observations. However, it is not practical for next generation lar…
Superresolution Interferometric Imaging with Sparse Modeling Using Total Squared Variation --- Application to Imaging the Black Hole Shadow
Kazuki Kuramochi, Kazunori Akiyama, Shiro Ikeda +5
We propose a new superresolution imaging technique for interferometry using sparse modeling, utilizing two regularization terms: the -norm and a new function named Total Sq…
